TNS-J02 Digital display torsion Testing machine This kind of testing machine is used for the torsion test for all kinds of materials, by imposing a torque. It's mainly suitable for material labs of scientific research deptartment, colleges or universities and industrial enterprises to test the mechanical properties of materials under torsion condition. There are two testing methods: Automatic testing: Turn the hand wheel until the test rod breaks. The testing machine will automatically test the yield torque M1 and the maximum torque M2. Manual testing: Choose the test angles and torques of any 9 points during the testing period and record them.
